Definitions

  • the invention relates to a method for meshing with a knitting machine and the use of a knitting needle in this method.
  • the splitting of meshes is a relatively frequently desired process in the manufacture of technically complex knits.
  • a mesh part is advantageous in the transition from a single-surface knitted fabric to a double-sided knitted fabric.
  • a piece of mesh also allows a whole range of knitting bindings that would otherwise not be produced.
  • the object of the present invention is to propose a method by which a genuine stitch splitting operation with latch needles is possible, and to provide a method of how a stitch splitting can be performed.
  • the beginning of the method according to the invention corresponds to the method for transferring a stitch from one needle to the opposite needle.
  • Enabling passage of the needle hook of the opposing needle between the loop leg and the needle shaft of the needle originally holding the loop can be achieved in a manner known per se by a spreading spring on the needle pushing the mesh leg outwards.
  • the stitching section allows, in contrast to the tongue needles usually used now to hold the stitch to be divided in this area and then to slide by a propulsion of the needle, the stitch in the needle hook, while the opposite needle already holds the stitch in her needle hook.
  • the stitch with its head and one leg on the original needle holding the stitch and the other leg in the hook of the opposite needle is carried out both on a flat knitting machine and on a circular knitting machine.
  • the object also relates to the use of a needle for knitting machines with a pivotally mounted and in an end position the needle hook closing tongue in a method according to the invention, in which between the tongue tip in the needle hook closing end position and the beginning of the rounded portion of the needle hook head a stitch support section is arranged ,
  • Fig. 1a the front portion of a latch needle 3 '' according to the prior art is shown.
  • the needle 3 "has a needle neck 32", a needle head 33 and a needle tip 35 at the end of the needle hook.
  • a tongue 31 is provided which is rotatably mounted about a pivot point D which lies on a line 100.
  • the tongue 31 is shown in its end position closing the needle hook.
  • the end 38 of the tongue covers the needle tip 35 and terminates immediately at the beginning of the rounded portion of the hook head 33. This means that a stitch that slides over the tongue 31 and the tongue tip 38 jumps directly onto the rounded portion of the hook head 33 and from
  • 1b shows a needle neck 32, which is opposite the needle neck 32 "of the needle 3 '' extended and has a correspondingly deeper needle hook. Also, the free leg 34 of the needle hook is longer here than in the needle 3 '', so that between the tip 38 of the tongue 31 and the hook head 33 results in a Mascheauflagesetation 40 on which a mesh can be held. This means that a by a retraction movement of the needle 3 via the tongue 31 and the tongue tip 38 sliding mesh first jumps on the mesh support section 40 and can be held there when the needle 3 is not retracted further. Only by further retraction of the needle 3, the stitch then slides over the hook head 33 in the mesh as in the needle 3 ''.
  • FIGS. 1c and 1d show alternative embodiments of needles 3 "', 3" "according to the invention, which are each likewise provided with mesh support sections 40', 40".
  • the free leg 34 'of the hook of the needle 3' '' has an approximately V-shaped recess 41, the tip of which is rounded off, and the rounding at the tip merges into a straight line 43 leading to the hook head 33, and on the opposite side into a straight line 42 which extends to the needle tip 35.
  • the recess 41 is in the needle 3 '' 'an even better grip of the stitch on the mesh support section 40' as in the Needle 3 given.
  • Fig. 1d shows a needle 3 "" which is very similar to the needle 3 "'of Fig. 1c.
  • the stitch support section 40 " is also provided with a rounded recess 44, but now merges with arcuate portions 45, 46 to the needle tip 35 and the hook head 33.
  • the needles 3 '' 'and 3" ", the Recesses 41, 44 formed by a corresponding undulating configuration of the free legs 34 'and 34' 'of the needle hook.
  • FIGS. 2 to 7 now illustrate how, with a flat knitting machine having two opposing needle beds 1, 2, which are equipped with needles 3, 3 'according to FIG. 1b, the division of a stitch 5 can be carried out.
  • Fig. 2 shows the stitch 5 originally holding the needle 3 on the needle bed 1 and arranged on the opposite needle bed 2 needle 3 'in its basic position.
  • the needle 3 is in the direction of arrow A away and in the direction of arrow B inwardly movable.
  • the needle 3 ' can drive out in the direction of arrow C. and retract in the direction of arrow B again.
  • the stitch 5 of the last knitted stitch row of the knitted fabric 4 is held in the hook space 36 of the needles 3 of the needle bed 1.
  • An unillustrated trigger moves the fabric 4 in the direction of arrow Z down. This pull-off force results in the stitch 5, which is supported on a tee wire 12, a tension which is necessary for the stitch formation and for a transfer operation to the needle bed 2 and for the stitch sharing method shown here.
  • a spreading spring 38 is also arranged, which spreads the leg 5 'of the mesh 5 laterally from the needle shaft. This makes it possible, with a spurt of the needle 3 'in the direction of arrow C, the hook of this needle 3' between the shaft of the needle 3 and the mesh leg 5 'pass, until the syringe 35' of the needle hook is above the stitch head 5.
  • the needle 3 ' is subsequently withdrawn in the direction of the arrow D until the loop 5 comes to rest within the hook space 36' of the loop 3 '.
  • the needle 3 is retracted in the direction of arrow B, to such an extent that the loop 5 closes the tongue 31 of the needle 3 and comes to lie on the extended leg 34 of the needle hook of the needle 3, as shown in FIG.
  • the stitch 5 is now so in the hook space 36 of the needle 3 'and at the same time on the mesh support section 40 and the leg 34 of the hook of the needle 3.
  • the needle 3 is now expelled again in the direction of arrow A, as shown in FIG shows.
  • Austriebsterrorism resting on the leg 34 stitch 5 opens the tongue 31 of the needle.
